Hi all,
Currently we have a quite large scale online chat-room, using MySQL /
Memcached for data store. Chat room message is refreshed every 2 - 10
sec (adaptive, depends on "chat rate", using Ajax).
Does that mean you use AJAX polling with a user configurable interval of
2 to 10 seconds to drive the chat?
This sounds like it could be the main performance problem. I would
expect some form of COMET or even the long request pattern to improve
your performance.
